SASci ABSTRACT Ethnographies of Indigenous Australian language groups suggest that their populations were consistently small, averaging perhaps 500 people each, while classical models of their kinship systems consistently embody endogamous marriage as both a norm and a logical requirement. However, paleodemographers argue that reproductively closed small human populations are doomed due to stochastic variations in birth rates and sex ratios. How did these societies avoid extinction and indeed persist in Australia for 40,000 years and more? We introduce a mathematical model of Aboriginal descent, marriage and kinship that is reproductively open rather than closed, show how the openness articulates with traditional closed models, and demonstrate how the resulting system maintains dynamic population stability despite internal and external stresses that might otherwise lead to extinction. Our resolution of this Australian Paradox demonstrates what mathematical modeling gets us.

Wednesday: Nov 16, 9:50-10:40.

    Abstract. Although the talk will focus only on civilizational networks as an example, many complex systems are composed by multi-nets, i.e., multiple networks undergoing change in time series. Understanding the behavior of multi-net systems poses some basic questions:
    1) how should we represent and model multiply layered and evolving networks (multi-nets) so as to discover their instabilities and nonlinear dynamics?
    2) what are some of the common properties induced by dependence on co-evolution with network topologies?
    3) does a generalized Boltzmann-Gibbs entropy, that takes into account network dependencies and hence long-range correlations, have applicability to modeling complexity in social systems?
    4) what is the contribution of a combination of multiply layered networks, time series, methods of study for nonlinear dynamic interactions (identifying oscillations and instabilities), simulation, nonextensive BG entropy, and tracking co-evolution of network topology?
    The examples illustrated are city attributes and networks, industrial networks, agent search behavior, and marriage choice; each includes issues of the co-evolution of network topology and micro-macro linkages. Five sets of results are discussed:
    1. A simulation that shows how modeling of results with generalized Boltzmann-Gibbs (q-) entropy takes long range correlations into account in known network dynamics relating to agent search behavior. http://arxiv.org/abs/cond-mat/0508028 SFI working paper (incoming comment: you might find interesting the paper about measuring growing mechanisms in networks (interaction behavior, or preferential attachment (PA)), especially regarding your neat recent arXiv paper, where perhaps it may be relevant in the particular case of PA related to degree (alpha), social distance (beta & gamma)

    Abstract of the discussion. The growth regimes of complex networks account for many of their structural features and behavioral effects. In the case of collaborative alliances among organizations in the biotech industry, the dynamics of inter-connection helps forge cohesive clusters of prominent nodes into an elite that can play gatekeeper and arbiter roles in an expanding network. The characteristics of such emergent elites, however, depend intimately upon the structural locations of the partners that form new ties (Powell et al., AJS 2005). Systems where cores deepen their internal connections conserve their position, but may calcify. Those that expand their reach by forming connections to newcomers and to the network's periphery increase responsiveness and innovation at the cost of incoherence. Analysis of twelve years of longitudinal network data from the biotech industry demonstrates that a mix of expansive and conserving ties account for that industry's particular combination of stability and responsiveness. A structural and dynamical view of network growth offers new insights into the distinctive features of social and economic networks, while linking models of network dynamics to debates in organizational theory and innovation studies. Analysis of dynamics shows interactive and periodic oscillation between consolidation within the multiconnected core of the industry and recruitment by core organizations of newcomers or peripheral partners in the network that have a high potential for innovation and complementarity.

    International SFI Collaboration on Network Analysis using Pajek: Powerpoint slides Civilizations as Complex Networks. Aug 23, 2004. Abstract. General scientific strategies for complex evolutionary processes emergent out of network interaction might require capturing long term dynamics first, in this case the interaction between relatively slow processes of population growth pressing on resources building pressures for sociopolitical violence, and how these affect stacks of processes that operate at faster time scales. Turchin's work shows oscillatory dynamics in multiple civilizational contexts at a secular (2-3 century) scale in which organizational innovation leaves lasting organizational changes that generate millennial trends. Micro dynamics resulting from demographic-violence crises in the period and region examined (1175-1500 CE Europe and peri-European region beginning with a largely demonetized economy) drive monetization at the macro-level and differential growth of commercial production regions that is mediated by network variables (placement in the geographic and trade network). Entailment relationships among commodities and urban or trade-node variables change over generational time scales - the current research problem involving how these coevolve with demographic-violence phases and regional network positional effects. Strong statistical tests are used for identifying empirical dynamics, changing entailment relationships, new graph theoretic measures and statistical techniques (ring cohesion) are used for measuring cohesion and its effects, and new network measures of flow centralities contribute to time-lagged predictions of changes in the relative prominence of cities and states within the evolving world economy.

    Santa Fe SASci meeting, Feb 2005, Title: Macromodels - Civilizations as Dynamic Networks

    Abstract: Here we present, critique, and examine the empirical evidence for a model of population growth that is more complex than either of the models power-law or hyperbolic. It involves two variables, a technologically induced carrying capacity K, and the literacy rate, in addition to population number P. Literacy rate L is seen as a critical nonlinear variable that has a sigmoidal pattern of change in relation to K, KL(1-L), while changes in K are affected by the product P times L and changes in P are affected by those in L times N but divided by L. Hence population growth slows as literacy increases, as in (a) the theory of demographic transition and (b) the periods of demographic transition over the past 12,000 years.

    Santa Fe SASci meeting, Feb 2005, Title: Conceptual Ethnography

    Abstract: Conceptual ethnography begins from the recognition that the compartments and conceptions of anthropology and ethnography are interlinked. Here I examine cognition and social networks in relation to the concept of culture, exemplified in the study of kinship. Concepts used in network analysis of the context and behaviors involved in kinship lead to new understandings of patterns of cohesion. Within cohesive groups, people in various communities are shown to use the network itself to compute categories of kinship in unexpected ways that do not require the kinds of assumptions anthropologists often make about the connection between kinship terminology and behavior. It is shown that this lends support to the view that cognition cannot be considered an internal mental process but involves the social environment itself as part of the cognition in the wild, as Ed Hutchins has aptly put the case. Hence culture cannot be considered in terms of models of internal states, and a definition of culture must deal with the many layers of interconnections between behavior, networks, cognition, and socially cohesive units such as community or organizations in which people interact. powerpoint

    Redondo Beach INSNA meeting, Feb 2005, Title: World-System Network Dynamics in the Early Renaissance

    Abstract: The European and surrounding region, 1175-1500, is examined as a portion of the larger world-systems interface, drawing on (1) Spufford's work on trade networks, urban industry, the dynamics of monetization and hyperinflationary processes and their effects and (2) Turchin's work on dynamics of population change and sociopolitical violence. Longitudinal analysis of generational time series for industries and trade routs in intercity networks integrates network analysis -- providing additional predictions about structural effects on change processes -- with statistical dynamics and the dynamics of change in interindustry implicational structures. Overlays of GIS and network data and images are used for visualization in addition to statistical analyses. powerpoint
